Dynamic Impedance 1.5SMC6.8 SERIES , MOTOROLA 3a ) MOTOROLA MOTOROLA SC (DIODES/OPTO) RESPONSE TIME In most applications, the transient suppressor device is placed In parallel with the equipment or component to be protected. In this situation, there is a time delay asso- ciated with the capacitance of the device and an over- shoot condition assoclated with the inductance of the device and the inductance of the connection method. The capacitive effect is of minor importance in the parallel protection scheme because it only produces a time delay in the transition from the operating voltage to the clamp voltage as shown in Figure 3. The inductive effects in the device are due to actual turn-on time (time required for the device to go from zero current to full current) and lead inductance. This inductive effect produces an overshoot in the voltage across the equipment or component being protected as shown in TYPICAL PROTECTION CIRCUIT Zin Vin - LOAD VL Vin (TRANSIENT) V VL Vin . tp = TIME DELAY DUE TO CAPACITIVE AFFECT t Figure 3. ese D MH 6367255 0081340 T T-H-Aa3 Figure 4. Minimizing this overshoot is very important in the application, since the main purpose for adding a tran- sient suppressor is to clamp voltage spikes. The 1.55MC6.8 series has very good response time, typically < 1.0 ns and negligible inductance. However, external inductive effects could produce unacceptable overshoot. Proper circuit layout, minimum lead lengths and placing the suppressor device as close as possible to the equip- ment or components to be protected will minimize this overshoot. Some input impedance represented by Zjyp is essential to prevent overstress of the protection device, This impedance should be as high as possible, without restricting the circuit operation.
